1. The problem statement, all variables and given/known data Let z = 2 + i and u = -3-3i. Calculate the value of |z/u|. 2. Relevant equations None. 3. The attempt at a solution |z/u|=|(2 + i)/(-3-3i)| = |(2 + i)/(-3-3i)*(-3+3i/(-3+3i)| --- if it is not clear, I'm multiplying by the conjugate. = |(-6+6i-3i+3i^2)/(9-9i+9i-9i^2)| = |(3i^2+3i-6)/(-9i^2+9)| = |(3i-9)/18| = |-1/2+i/6| = 1/2+i/6 Did I take care of the absolute value part correctly? Thanks.
